After that i wants to make the sequence.FASTA file in my project folder. And I wants to execute batch file with parameters as blastp.exe file, sequence. FASTA file, database files, output file.
There is no problem in the file creation of sequence.FASTA
ERROR IN: the batch file is not execute, So the I am not able to get the output file for display.
ERROR is : java.io.FileNotFoundException: D:vaibhav_workspace.metadata.pluginsorg.eclipse.wst.server.core mp4wtpwebapps oxin-dataoutputprotein.txt (The system cannot find the file specified)
Technologies Used :JSP,Servlet,Process-builder
I have the following code as :
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out=response.getWriter();
String values=request.getParameter("t1");
ServletContext servletContext = request.getSession().getServletContext();
servletContext = request.getSession().getServletContext();
String path="//sequence.FASTA"; /*file is created in getRealPath()*/

Batch File With Some Relative Folders
Jul 17, 2014Batch file (. BAT) problems with some folders on. I created an application in Java and put the JRE folder within the application, because some users do not have Java installed on your machine and the way I did, my application runs. JAR with the JRE that is contained in my application but I created a BAT file that contains the following command:
start "" jre8 bin javaw-jar app.jar
So I run my program in java through the file. BAT calling JRE that is inside the folder and then this JRE runs the mine. JAR and works great anywhere in windows, worked well on a USB key with this command is within. BAT (start "" jre8 bin javaw-jar app.jar).
BAT in certain folders, eg Program Files and Program Files (x86), I need this code to be able to find any directory, regardless of whether the directory has spaces in the name, symbols, numbers or anything else, because maybe people will put the application folder to another location or rename the folder, and if this happens the program will stop working? And especially do not give problems to run inside the Program Files and Program Files (x86) because the application runs everywhere except in these two folders.

View Replies View RelatedJava Loses Focus When Printing
Aug 1, 2014I am working on a Java program to monitor meal consumption by members of an organization. They swipe their ID cards, enter PIN, and number of meals they want. System knows if dining room is open and what meal based on time. The system then prints out a receipt on an Epson TM-T88IV receipt printer.
The system is running in console mode. My problem is that when the system prints, a Notepad window pops up for milliseconds and then the Java program loses focus. The screen reverts back to Windows home screen. I'm using Windows XP, SP3 and the latest Java build.
How to prevent the loss of focus?

How To Play WMA Or MP3 Files In Java
Jan 23, 2014I was looking at the Sound API pages in the java tutorials. I was planning to use it to run wma files. Fortunately, for me, I found, soon into the tutorials, that these API DON'T support the type I have all of my files in (I have a ton of wma files but none of the libraries mentioned support them.)
I almost thought I heard JavaFx or whatever it's called does, but that sounds foreign and Netbeans lists it as a separate type of java in a way, so I don't know if it would be cross-platform or if it could work with the JavaSE API.) Nor do I know what JavaSX or whatever it's called is really, other than that it's more for internet than application.
If I wanted a JPanel or Applet acting as the content pane of a JFrame or being in a JFrame, could I use JavaFX (or whatever it's called) or some third party library (that I always tend to end up spending hours on trying to get it to find the jar files when I import them, so I hope I don't need too many jar files!!!! ) would it work with the JavaSE API?
I don't know much about Java and playing sounds (other than that there is a static method, I think under Toolkit, that will play a system beep) with programs.
However, I can see that that packages don't support certain types (so much for cross-platform!!!!!!! ) and also that a while back that Oracle took over and that they aren't really updating the Java Sound APIs really that much at all
So, without having to learn a whole new Java set of standards (assuming JavaFX or whatever it's called is a different set of standards from JavaSE), is there a way to play .wma?
That's all I seem to have on my computer.
(I suppose I could create new sounds, though if Oracle isn't updating the library, who knows if even that works anymore, but if you're trying to run a Java Media Player that runs lots of DIFFERENT sound file types, this seems a real setback. )
I heard you could convert them to MP3s (I heard there were free things that did it, but who knows if the things aren't filled with viruses that'll do it or, even if they're not, that they'll really mess up the quality of the sound and that I might lose the old .wma file in the process even if it doesn't corrupt the sound.)
But, even if I get a .mp3, I heard the main JavaSE libraries DON'T cover that either, though it was said it was easier to make it run them than .wma files.
MediaPlayer and the main JavaSE classes don't seem to be able to fit for this type of program (a java media player) that I was planning. Heck, they can't even play any music I have on my computer at all, media player or not.

View Replies View RelatedRenaming Files With Java
Mar 31, 2014I have a batch of files that I want to remove a common word from all of their filenames. I think I could bash my way through this if I had a linux machine, but I don't. Any tips on what classes I need for the files I want to rename (if any) would be great. I can handle the string changes, but searching a directory and renaming files is something I've never done with code before.
View Replies View RelatedSecure Java Files
Oct 4, 2014My friend has a youtube channel with 50.000 - 100.000 subscribers. I dont know the exact amount but he asked me to make a program for his subscribers. I made it in Java and it works perfectly fine but now i want to make it secure so people can't decompile it and read/change the code. Because ofcourse he also has viewers who can hack programs.
But i dont know how i can do that. I dont want to make the code hard to read. I already heard about program which adds lines of code without doing anything actually and programs making the code a lot more complicated. But thats not what i want, i want to make the Class files undecompilable so people cant decompile it to Java files again and read the code.
I know this is possible, Runescape for example is written in Java too and secured good enough in my opinion. I know there are fake Runescape games called private servers or something like that. But its not easy as downloading the game, decompiling it, connecting it to another server and you're done. A little kid can do that but i think its even possible that people just programmed Runescape again from scratch.So i want to make my program very hard to decompile or even impossible, i want it as impossible as possible.

Best Way To Read / Write Files In Java?
Mar 31, 2014I have seen different methods of creating and reading files (specifically text files) in Java. The PrintWriter method or the Formatter with a Scanner to read the file, using a BufferedWriter with a BufferedReader, etc. They will all read/write text files, but from what I understand they do so in different ways. When would it be more beneficial to use a buffered writer than, say, PrintWriter, which is much simpler code-wise? Is there a "best" way to handle i/o in general in Java?
